SubMIP Node Limit
Type : Integer
Range : {1 .. 2100000000}
Default : 500
The option sets the number of nodes explored when CPLEX is solving a subMIP of a MIP. SubMIPS are described in the section ‘SubMIP’ of the CPLEX 20.1 help.
Note
This rarely used option is helpful only in rare “corner” cases where there is clear evidence that the default limit is really inappropriate for this particular problem.
